The Sport Motivation Scale-II (SMS-II) and Behavioral Regulation in Sport Questionnaire (BRSQ) assess motivation regulation in sports based on Self-Determination Theory. This study compared their psychometric properties, revealing key differences. While the BRSQ demonstrated generally acceptable reliability, the SMS-II showed reliability issues in introjected, external, and amotivation subscales. Both scales faced convergent and discriminant validity challenges, particularly in distinguishing adjacent motivational constructs. Model fit required post-hoc adjustments (e.g., error correlations, item removal) to achieve acceptability. Invariance testing confirmed applicability across groups, but correlations within the motivational continuum deviated from SDT’s quasi-simplex pattern, likely reflecting motivation’s dynamic nature. These findings highlight the need for critical evaluation of motivation measures, emphasizing context adaptability. While the BRSQ appears more robust, neither scale is flawless, suggesting cautious interpretation of scores. Researchers should prioritize instruments aligning with their specific objectives and account for potential psychometric limitations. This study reinforces the importance of refining tools to better capture motivation’s complexity in sports.
